摘要:目的:探讨5·12汶川8.0级地震中颅面部外伤的影像学表现特点。方法: 回顾性分析自2008年5月12~31日因地震颅面部外伤在我院行CT、MRI检查的伤员251例,其中CT检查248例,MRI检查16例。结果:放射检查阳性162例,阳性率为64.54%,以40～49岁年龄组最多,为53例,其中男性41例。在放射检查阳性中,多发伤112例(约69.13%),多类型颅面部外伤同时并存103例(约63.58%)。主要损伤发生率依次为软组织损伤(35.50%),骨折(22.94%),脑挫裂伤(21.21%),硬膜下及硬膜外血肿(10.40%),其它(共约9.92%)。结论: 地震造成颅面部外伤人群主要为40～49岁中年男性,多发伤、多类型颅面部外伤多见,并以软组织损伤、骨折、脑挫裂伤、硬膜下及硬膜外血肿较常见。Abstract: Objective: To describe the imaging features of head and face injured patients after the Wenchuan earthquake. Methods: The radiological information of 251 victims who were suspicious of head and face injury and underwent CT or MRI examinations from 12 May to 31 May 2008 was analysed retrospectively. There were 248 and 16 cases underwent CT or MRI examinations respectively. Results: One hundred and sixtytwo cases(64.54% )were positive. There were 53 cases in the 4049 years old age group, of which 41 were male. In patients with positive findings, 112 cases (about 63.58%) were comprised of several types of head and face injury. The incidence of the main injury type included: soft tissue injury (35.50%), fracture (22.94%), cerebral contusion (21.21%), subdural and epidural hematoma (12.40%), others (9.92%). Conclusions: The males with head and face injury in 4049 years old group were the major injured people in this earthquake. Head and face injury accompanied by multiple system injuries, the existence of several types of head and face injury at the same time were common. Among all the injury types, soft tissue injury, fracture, contusion, subdural and epidural hematoma were relatively commom.
